Dendritic cells (DC) have been tested in cancer immunotherapy clinical trials for two decades. Over this time, the methods of DC culture (or manufacture) have evolved, the approaches for antigen loading have broadened, the maturation signals have varied and different sites of administration have been tested. The post-vaccination immunologic questions asked have also varied between trials and ov...

Dendritic cells (DCs) play a central role as major targets of dengue virus (DV) infections and initiators of antiviral immune responses. Previous observations showed that DCs are activated by infection, presumably acquiring the capacity to promote cell-mediated immunity. However, separate evaluations of the maturation profiles of infected and uninfected bystander cells show that infection impai...

In the presence of proliferating cell nuclear antigen, yeast DNA polymerase (Pol ) replicated DNA at a rate of 40–60 nt/s. When downstream double-stranded DNA was encountered, Pol paused, but most replication complexes proceeded to carry out strand-displacement synthesis at a rate of 1.5 nt/s. In the presence of the flap endonuclease FEN1 (Rad27), the complex carried out nick translation (1.7 n...

background: nowadays, highly specific aptamers generated by cell selex technology (systematic evolution of ligands by exponential enrichment) are being applied for early detection of cancer cells. prostate specific membrane antigen (psma), over expressed in prostate cancer, is a highly specific marker and therefore can be used for diagnosis of the prostate cancer cells. the aim of the present s...

Cross-presentation of endocytosed antigen as peptide/class I major histocompatibility complex complexes plays a central role in the elicitation of CD8(+) T cell clones that mediate anti-viral and anti-tumor immune responses. While it has been clear that there are specific subsets of professional antigen presenting cells capable of antigen cross-presentation, identification of mechanisms involve...

Background: Dendritic cells (DCs) are potent antigen presenting cells for triggering of the immune reaction post transplantation. These cells are centrally involved in the initiation of T cell-dependent immune responses. Objective: To compare the level of DC maturation and function in liver transplant recipients with healthy controls. Methods: In this study, twelve peripheral blood samples we...
